Overachiever in power and sonicsI bought this about six months ago, and I haven't regretted this purchase! I only do two-channel even with video, and use this to drive B&W 683 loudspeakers. I was unsatisfied with my Denon 2807 AV receiver, so I began auditioning integrated amps. WOW. At 70 watts/channel, this baby rocks! It blows away the Denon which had 110 per channel, and sounds much better while doing it. It controls the B&W speakers like a much larger amp. The PM8003 has excellent detail, clarity, and slam. I can't distress this amp, no matter what I play! And movie soundtracks have so much impact, I question the need for a subwoofer. In my cabinet, the Denon receiver ran rather hot, but this Marantz runs quite cool. Compare this unit to amps rated at 100-125 watts per channel, and you will appreciate how underrated this amp is. You will enjoy this little integrated amp!
